Abstract
A low dropout regulator circuit with reduced overshoot and undershoot during transient state is discussed. The low dropout regulator circuit has a power device operating at a restive region, a first amplification stage and a second amplification stage. The first amplification stage amplifies a difference between a feedback voltage and a reference voltage to generate a positive signal and a negative signal. The feedback voltage is derived from an output voltage via a feedback resistor network. The second amplification stage amplifies a difference between the positive signal and a sum of a feed forward signal and the negative signal to generate an amplified signal. The feed forward signal is derived from an output voltage via a capacitor network.
